Question

If the speed of a car with a turbo engine can bemodeled as a function of time using the parabolic
equation s(t) = 2t^2?, how many seconds will it take the car to exceed the 60 mph?

Answer 1

Answer:

t = 19692 seconds

Step-by-step explanation:

Given that,

The speed of a car with a turbo engine can be modeled as a function of time using the parabolic  equation

$s(t) = 2t^2$

We need to find the time taken by the car to exceed the 60 mph.

Put s(t) = 60 mph

So,

$60=2t^2\\\\t^2=30\\\\t=5.47\ h$

or

t = 19692 seconds

So, the car will take 19692 s to to exceed the 60 mph.
